Improved Attitude and Heading Reference System

Inertial Aerosystems is introducing an enhanced version of its established MTi-G product. This device, manufactured by Netherlands-based Xsens Motion Technology, is a MEMS Attitude and Heading Reference System (AHRS) with integrated GPS and barometer. It provides accurate horizontal and vertical position, velocity and 3D orientation estimates. It incorporates an internal ultra low-power signal processor and a real-time Kalman filter.

+++ STOP PRESS 2 November 2011 - This product is no longer available from ETLG Inertial Aerosystems, but contact the company for information about its other navigation and positioning sensors. +++

This enhanced version has a new GPS receiver that offers 50 tracking channels instead of 16. This gives a faster GPS recovery after (short) signal outages within challenging environments. The MTI-G has a faster GPS fix, and the fix is more stable. The velocity output from the device is improved by using carrier phase tracking from the GPS receiver. The new GPS receiver is prepared for GALILEO L1 open service. In the case of the GPS fix being lost, the GPS receiver will use 50 channels to restore the fix.

Able to operate in tough environments within a temperature range of -20 to +55degC, the device weighs only 68g and measures 58 x 58 x 33mm, making it suitable for applications where space and weight are at a premium.

The MTI-G is an excellent measurement unit for navigation and control of vehicles, other objects and even humans. Applications include aerospace, automotive, robotics and marine industries, as well as pedestrian navigation and virtual reality.
